SPlNDLE-BEARING.

SPECIFICATION forming part of Letters Patent No. 602,110, datedApril 12, 1898. Application filed September 25, 1897. Serial No. 653,038. (No model.)

WORTH and THOMAS HIGGINBOTTOM, of Lowell, in the county of Middle'sex and State of Massachusetts, have invented certain new and useful Improvements in Spindle-Bearings; and we do hereby declare thefollowing to be a full, clear, and exact description of the in? vention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to an improvement in spindle-bearings and it consists in certain novel features of construction and combinations and arrangements of parts, as hereinafter set forth, and pointed out in the claim. In the accompanying drawings, Figure l'is a sectional view of our improvements. Fig. 2 is an elevation. Figs. 3 and 4 are cross-- sections, and Figs. 5 and 6 are detail views. A represents the bolster-casing, and B the bolster therein, said bolster being provided at one end with a groove or notch 1 for the reception of a key 2, whereby to prevent said bolster from turning. The lower end of the bolster-casing is made with a screw-threaded hole 3 for the reception of a screw 4, having a milled head 6 whereby to turn it. The upper end of the screw 4 is made with a socket for the reception of a step 7, on which the spindle O is supported, said step being loosely connected in the socket in the screw by. means of a pin a, so as to overcome vibration of the spindle.

The screw 4 may be made of any desirable metal, while the step 7 is preferably made of steel. In order to hold the screw and step carried therein in any position to which it may be adjusted, a jam-nut 8 is employed. By the construction and arrangement of parts above described the spindle can be adjusted while running to compensate for wear between the conical spindleand the conical in terior of the bolster by means of the screw 4. By removing the screw and step carried thereby any dust or other foreign matter which may have collected between the spindle and the bolster can be allowed to escape, and this may also be done while the spindle is in motion.

The bolster-casing A is provided at a point between its ends with an annular enlargement 10, on which a diagonal tube 11 is disposed, said tube being made to communicate with a diagonal hole 12 in the annular enlargement, and said hole is adapted to direct oil from the tube to the spindle.

The upper end of the diagonal oil tube or receptacle 11 is provided with an enlargement 13, to which an arm or cover 14 is pivotally connected. The arm or cover 14 is provided with a stop or shoulder 15 to abut against a similar stop or shoulder 16 on the enlargement 13, and said cover is maintained normally closed (with the stops abutting against each other) by means of a spring 17. The inner end of the arm or cover 14 is made with a projection 18, which constitutes a doffer-guard and projects just over the whirl 19 on the spindle and ins uch proximity thereto as to permit the free revolution of the spindle, but at the same time sufficiently close to the upper face of the whirl as to prevent play and lost motion of the spindle within the bolster and on the step, said doffer-guard also serving to prevent the spindle from being displaced when a bobbin is being do'ffed. These results are attained'by connecting the arm or cover 14 by means of a vertical pivot, so that said arm or cover canbe swung horizontally when it is desired to replenish the oil in said tube or receptacle, and the lubricatingoil can be poured into the receptacle while the spindle is in motion by merely swinging said arm or cover on its Vertical pivot.

By disposing the oil tube or receptacle in an inclined position the oil will flow down by gravity and there will be no danger of the lubricant lodging in parts of the tube or receptacle, as is the case where an angular oilreceptacle is employed.

The doftlng or removingof the bobbin from the spindle takes place many times each day, and as the doffer-guard must during this operation be'in position to prevent the undue lifting of the spindle it (the doffer-guard) becomes a detector to indicate the position of the reservoir-cover, the latter being necessarily covered when the doffer-guard is in position to prevent the undue lifting of the spindle. If during the dotting the spindle be lifted with the bobbin, the operator will thus be notified that the cover of the reservoir is out of position and he will then close the same.

The spindle and whirl can be readily removed, if desired, by simply turning the doffer-guard out of line with the Whirl.

Our improvements are very simple in construction, are cheap to manufacture, comprise but few parts, and are effectual in all respects in the performance of their functions.

Slight changes might be made in the details of construction of our invention without departing from the spirit thereof or limiting its scope, and hence we do not Wish to limit ourselves to the precise details herein set forth.

Having fully described our invention, what WILLIAM M. RUSHWVORTH. THOMAS HIGGINBOTTOM.
